history

Project history and usage

Credo is an Elixir static analysis tool focused on teaching and code consistency. It is commonly added as a Mix development/test dependency and run with mix credo to report refactoring opportunities, complex code, common mistakes, naming inconsistencies, and style issues.

Project history

The official changelog identifies version 0.1.0 as the initial release. Early releases added CLI behavior, issue categories, per-function lint support, custom checks, generated configuration, and support for project-specific .credo.exs files.

Adoption history

Credo became part of normal Elixir project hygiene because it fits the Mix workflow and publishes documentation on HexDocs. The README also documents editor and automated-code-review integrations, which helped make it useful both locally and in CI.

How it is used

The README recommends adding {:credo, "~> 1.7", only: [:dev, :test], runtime: false} to mix.exs, running mix deps.get, and then running mix credo. Configuration is usually generated or maintained in .credo.exs.

Why package nerds care

For package maintainers, Credo is the Elixir ecosystem's familiar lint-style dependency: it ships through Hex, exposes a Mix task, can fail CI through exit status, and has enough formatter and integration surface to appear in editor, CI, and code-review pipelines.
